上面的錯誤解決需要熟悉 #與$的差別（參下）
MyBatis/Ibatis中#和$的區別

結合以上（關鍵錯誤點 near ” and 1=1 ’ limit 0,5’ at line 3）
我的解決辦法將#替為$（不推薦）
推薦寫法（在Controller層中 將要搜尋的條件put進Map 集合 然後傳參 在mapper.xml 中遍歷 這樣更安全 ）
順便熟悉一下mybatis 傳參

一、單個引數：

public List getXXBeanList(String xxCode);

　　select t.* from tableName t where t.id= #{id}

其中方法名和ID一致，#{}中的引數名與方法中的引數名一直

select 後的欄位列表要和bean中的屬性名一致， 如果不一致的可以用 as 來補充。

二、多引數：

public List getXXXBeanList(String xxId, String xxCode);

　　select t.* from tableName where id = #{0} and name = #{1}

由於是多引數那麼就不能使用parameterType， 改用#｛index｝是第幾個就用第幾個的索引，索引從0開始

三、Map封裝多引數：

public List getXXXBeanList(HashMap map);

　　select 欄位… from XXX where id=#{xxId} code = #{xxCode}

其中hashmap是mybatis自己配置好的直接使用就行。map中key的名字是那個就在#{}使用那個

四、List封裝in：

public List getXXXBeanList(List list);

　　select 欄位… from XXX where id in
　　
　　　　#{item}
　　

foreach 最後的效果是select 欄位… from XXX where id in (‘1’,’2’,’3’,’4’)
